Lindsay Hwang, MD
Dr. Lindsay Hwang is a radiation oncologist and specializes in treating benign and malignant tumors of the central nervous system (CNS). She received her undergraduate degree in Human Biology from the University of California, San Diego and her medical degree from Case Western Reserve University School of Medicine. She completed her radiation oncology residency at USC and served as chief resident in her final year. She was awarded the RSNA Roentgen Resident Research Award for her research in brain metastases and patient advocacy. She brings extensive experience in today’s most advanced modalities in radiation oncology to treat patients with CNS malignancies. She specializes in Gamma Knife and other radiosurgery techniques, which use noninvasive, precise, focused beams of radiation to treat tumors. She also has expertise in intensity-modulated radiation therapy (IMRT), image-guided radiation therapy (IGRT), and stereotactic body radiation therapy (SBRT), among others. As a radiation oncologist, Dr. Hwang cherishes the privilege of guiding her patients through the vulnerable journey of cancer diagnosis and cancer care. Her goal is to deliver comprehensive, safe radiation treatment while developing a relationship of trust built on scientific expertise, empathy and consideration for patients and their families as whole individuals. Through the USC Brain Tumor Center, she is able to combine her passion for patient care while advancing the field through collaboration and clinical trials.

Lauren Smith, PhD
I am currently a senior medical physics resident in radiation oncology at the University of California Los Angeles. I  completed my PhD at Western University in London, Canada in 2016 with a research focus of using advanced functional MRI techniques to study the impact of diet on physiology of the liver and placenta. I am interested in adaptive therapy and MR-guidance in radiation therapy and am looking forward to joining Memorial Sloan Kettering Cancer Center in Manhattan as a faculty physicist this fall.



Cara Sullivan, BS, CMD RT(T)

Steve Pai-hsun Lee, MD, PhD
Dr. Lee is currently a staff radiation oncologist at Long Beach VA while holding a simultaneous faculty appointment at his alma mater, UCLA.

Dr. Lee immigrated to the United States from Taiwan at the age of 15. He attended public school in Los Angeles, and received his B.S. degree in Physics at UCLA in 1984. During his college years, he developed an interest in the integration of physics and biology and decided to pursue his graduate training in Medical Physics. He received such M.S. degree in 1986 after working on a NIH funded neutron therapy project at UCLA. Determined to be a radiation oncologist, Dr. Lee then received his M.D. degree in 1990 at the Ohio State University College of Medicine. He returned to UCLA and completed his residency training in 1995, while aiming to simultaneously pursue a Ph.D. in Radiation Biology under the world-renowned radiobiologist Professor H. R. Withers. In 2001, he finally realized this goal after years of juggling between clinical training, graduate study, laboratory research and even private practice.

Dr. Lee began his academic career at UCLA in 2000 and became a Professor of Clinical Radiation Oncology in 2011. In the meantime, he served as its Radiation Oncology Residency Program Director from 2003 to 2010 and Interim Chair from 2004 to 2008. In 2014 he was recruited by Department of Veterans Affairs as its VISN 22 Chief of Radiation Oncology to oversee radiotherapy services at both Long Beach and West L.A. VA medical centers. He became Chief of Radiation Oncology service at Long Beach VA in 2019.
